APPLICATION FILED JULY3, 1914.

Patented Apr. 27, 1915 Bonn cos'rnn, or MARION, INDIANA.

TORCH.

To all whom it may concern:

Be it knownthat I, BURR Marion, in the county of Grant and State of Indiana, have invented certain new and useful Improvements in Torches; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will'enable others skilled in the art to which 1t appertains to make and use the same.

This invention relates .to improvements in -to.rches,-one'object of-the invention being to so constructthe device that it may be used either as a welding or an illuminating torch, and to provide meanswhereby the operator may easily and quickly manipulate the same with the use of one hand to transform the device from one character of torch to the other.

A further object is to provide simple and efficient means for controlling the quantity and mixture of gases employed to effect an illuminating flame or a welding flame of the desired volume or intensity.

With these and other objects in view, the

I V invention consists in certain novel features is a view partly in section and partly in acetylene gas of supply. The chamber of this cylinder or of construction and combination of. parts"as hereinafter set forth and pointed out in the claims.

In the accompanyingdrawings, Figure1 1 e evation illustrating my improvements. Fig. 2 is an enlarged sectional view showing the valve mechanism. Fig. 3 is a separate view in elevation of the valve, and Fig. 4 is an enlarged detail sectional view showing the connection between the oxygen and'acetylene pipes. I

1 represents a valve. casing, to which two cylinders or receptacles 2, 3 are suitably secured (preferably in front and in rear respectively of said casing), and communicate with the latter by means of ducts 1-5 and ports 6-7. A pipe 6 communicates with the cylinder or receptacle 2 for conducting thereto from a suitable source receptacle may contain a quantity of me tallic shavings, such as 'steel moss, and in order to prevent the shavings from entering the duct 4 and pipe 6 diaphragms 7 of wire netting may be employed.

A pipe 8 is connected with the casing 1 and communicates with a port 9 therein to receive acetylene gas in the manner herein- Speciflcation of Letters Patent.

Application filed m a, 1914. Serial No. 848,843.

(DUSTER, a citizen of the United States, and a resident of Patented Apr. 27, 1915.

after described,-the forward portion of said pipe 8 being curved and provided at its free end with a burner head .10.

A; pipe 11 (adapted for connection with a .suitable source of oxygen supply) is connectedwith the casing 1 so'as to communicate with a port 12 located therein opposite the port 7.

, The cylinder 3 has connected with its forward end, a. pipe 13 (preferably smaller in size. than the pipe 8) and the forward portion of said pipe 13is 'bentto lie alongside the. pipe 8,-'the forward end of the pipe 13 being. connected with the pipe 8 by means of a tubular nipple 14 which enters both of said pipes and is made with perforations communicating with the respective pipes. The. -f cylinder 3. may contain metal clippings (preferably brass or bronze), and said clippings are prevented from entering the port and. pipe 13 "by means of diaphragms 15 h of wire netting. r

The supply of acetylene gas or oxygen or both to the burnerhead, may be readily controlled and regulated by. means of valve devices disposed between the ports 6-9 and 712. These devices comprise a conical plug valve 16 mounted in a suitable bore in the casing 1 and provided at its with a stem.17 depending below said casing.

lower end Two collars 18-19 are located on thestem 17, near respective ends thereof and between these collars, a spring 20 is located on the stem and serves to retain the plug valve properly in place and to compensate for wear. The plug 16 is provided in its lower portion with a transverse duct 21 located at one side of the longitudinal center of the plug and adapted to .connect the ports 12 and 7. For the purpose of permitting the plug to be readily turned by the operator to- I control. the supply of oxygen, provided with a finger lever 22 projecting laterally therefrom, and to limit the rotary movements of the plug, the latter is provided with a pin 23 movable from end to end of a slot 24 in the upper portion of the casing 1. p

The plug 16 ismade with a. duct 25 to communicate with the port 6 in the casing, and said plug is also made with a duct 26 to communicate with the port 9,-said ducts 25 and 26 being also adapted to communicate with each other. A valve 27 extends downwardly into the upper portion of the plug said plug is" 16 so as to intersect the ducts 2526 and,

control the passage of acetylene gas-through these ducts. The valve 27 is made with a threaded portion 28 to meshwith a similarly threaded portion within the plug and the upper end of the stem of this valve is provided with a hand wheel 29 to facilitate the manual operation of the same. The upper end of the stem of the valve 27 passing through a packing box 30 screwed onto a threaded shank 31 at the upper end of the plug 16. v

It will be observed that the ends of the ducts in the plug 16 are each of less diameter than the diameter of the respective ports 6, 7, 9 and 12 and that the duct 21 in the plug is at one side of the axis of the plug. By this arrangement, the plug may be turned to such position as to c0nnect the acetylene gas ducts 25-26 with their ports, while communication between the oxygenports 712 is kept closed, or so that the ducts 25-26 and 21 may be caused to communicate with their respective ports and thus permit the iupply of both gas and oxygen to the burner ead.

When it is desired to use the torch for welding purposes, the plug will be turned by means of the finger piece 22 in such manner as to permit the supply of both acetylene gas and oxygen to the burner head. The amount of the mixture may be regulated by the extent to which the plug is turned, while the relative proportions of gas and oxygen may be regulated by means of the valve 27.

When it is desired to use the device temporarily as a lighting torch to permit the operator to inspect his work,this may be quickly accomplished by turning the plug sufficiently to close the duct 21 and opening the valve 27 more or less to control the suppl; of onl acetylene gas. The device may be as quic ly again converted into a welding device by reversing such manual operation of the valve mechanism.

Having fully described my invention what I claim as new and desire to secure by Let'- ters-Patent is: 1

1. In a torch, the combination with two cylinders, and a casing disposed between said cylinders and communicating with both,

of a gas inlet pipe communicating with one of said cylinders, an oxygen inlet pipe communicating With said casing, a gas outlet- -valve mounted in the plug for separately controlling passage of gas through the gas pipe to the burner head. v

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
